X-rays vs metal detectors
While airport security scanners use X-rays to check bags, they can also use metal detectors or metal wands to check for metallic objects. X-ray machines use electromagnetic radiation to detect physical contaminants through density differentiation. The X-rays pass through less dense materials with ease, while more dense materials absorb more of them and appear darker in the resulting image.
Metal detectors, on the other hand, rely on the disturbance caused by the conductive and magnetic properties of metal. They create electromagnetic fields and rely on the differences in magnetic permeability across substances to reveal contamination. Metal detectors can detect specific kinds of metal very well because of their magnetic properties. However, they may not be compatible with all packaging types, including complex metalized packaging that can cause inaccurate readings.
X-ray machines can detect a wide range of non-metal contaminants, including glass, stone, some plastics, and calcified bone pieces. They can also detect product defects such as missing or broken products and underfilled packages. They are also able to detect much smaller metallic contaminants than metal detectors.
In the context of airport security, X-ray machines are generally considered safe for laptops as they use a specific wavelength of light to operate. Hard drives store their data as magnetic media and are therefore unaffected by airport X-rays. However, metal detectors send out a strong magnetic pulse that can erase hard drives. Hence, it is recommended to avoid taking laptops through metal detectors.

Laptops safe from X-rays
There is a lot of discussion around the possibility of airport X-ray scanners causing damage to laptops and other electronic devices. Many people have shared their experiences of laptop damage after going through airport security. However, it is important to understand the technology behind X-ray scanners to assess the risk to laptops.
X-ray particles are created by accelerating electrons from a copper cathode to a tungsten anode through a voltage drop. The collision between the electron and the anode results in high-energy photons, or X-rays. These X-rays are then directed towards the object being scanned, and an image is formed by capturing the shadows of objects that block the X-rays. Modern scanners can even colorize the image based on density ranges.
Laptops and other electronic devices do not contain biological tissue or DNA, so they are not affected by X-rays in the same way that biological tissue is. Hard drives, for example, store data as magnetic media, and X-ray machines use a specific wavelength of light that does not impact this type of data storage. While hard drives are sensitive to magnets, they are impervious to all forms of light, including X-rays. Therefore, passing through an X-ray machine at airport security will not damage a laptop's hard drive.
However, it is important to distinguish between X-ray scanners and metal detectors. Metal detectors use strong magnetic pulses that can erase hard drives. Therefore, it is recommended to avoid taking your laptop through a metal detector and always opt for the X-ray scanner when given the choice. Additionally, it is always a good idea to back up your important data before travelling, just in case of any unforeseen issues.

Laptops damaged by metal detectors
It is rare but possible for laptops to be damaged by airport security scanners. However, this damage is not caused by X-ray scanners, which are generally considered safe for laptops. Instead, the damage is often attributed to metal detectors, which use strong magnetic pulses that can erase hard drives.
X-ray airport scanners are not considered harmful to laptops. X-rays use high-energy photons to create images of objects that don't allow X-rays to pass through them, such as laptops. While X-rays can be ionizing radiation that harms biological tissue, electronics are not made of biological tissue and are not affected by X-rays in the same way.
Despite this, some travellers have reported issues with their laptops after passing through airport security. These issues include poor Wi-Fi reception, distorted screens, and fried hard drives. In one case, a MacBook Pro stopped working altogether and only showed a grey screen after going through an airport scanner.
To avoid potential damage to laptops, some sources recommend avoiding metal detectors altogether when passing through airport security. Instead, travellers can opt for X-ray scanners or hand inspections for their laptops. It is also recommended to keep laptops in carry-on baggage and ensure they are securely packed to minimize the risk of damage during the screening process.
While the chances of laptop damage from airport security scanners are low, taking simple precautions can provide peace of mind and help ensure the continued functionality of electronic devices during and after air travel.

Phones and laptops in airport security
Airport security scanners use X-rays to create live imaging to check your bags. X-ray particles are created by accelerating electrons from a copper cathode to a tungsten anode through a voltage drop. The collision between the electron and the anode results in heat and high-energy photons, which are X-rays. These X-rays are then directed at the object to be scanned, creating an image. Objects that block X-rays, such as phones and laptops, show up as dark areas on the image.
While X-rays can be harmful to biological tissue in large doses and with frequent exposure, they do not affect electronics in any significant way. This is because electronics are not made of biological tissue and do not contain DNA. Hard drives, for example, store data magnetically on rotating platters, and while they are sensitive to magnets, they are impervious to all forms of light, including X-rays.
However, there have been reports of laptops and phones being damaged after passing through airport security. Some travellers have reported issues with their laptops, such as distorted screens and poor Wi-Fi reception, after going through X-ray scanners. Similarly, some smartphone users have reported their devices malfunctioning or stopping working completely after airport security checks.
To minimise the risk of damage to your electronic devices when passing through airport security, it is recommended to avoid taking them through metal detectors, as these use strong magnetic pulses that can erase hard drives. Instead, allow your devices to pass through X-ray machines, and if possible, request a hand inspection. Additionally, ensure your devices are fully charged and turned on before passing through security, as this may deter overzealous security personnel from wanting to inspect your devices further.

Laptops: hand inspection vs X-ray
When it comes to airport security, there are two primary methods of screening laptops: hand inspection and X-ray scanning. Both methods have their own advantages and considerations, and understanding the differences can help travellers make informed decisions about their electronic devices.
Hand Inspection
Hand inspection involves a manual check of a laptop by security personnel. This process typically requires travellers to power on their devices to demonstrate functionality. While hand inspection may be preferred by some as it avoids exposure to X-rays, it comes with its own set of considerations. Firstly, there is a risk of human error during the inspection, which may lead to potential damage. Additionally, the process can be time-consuming, especially if multiple devices need to be inspected. In some cases, travellers may feel uncomfortable allowing strangers to handle their personal devices due to privacy concerns.
X-ray Scanning
X-ray scanning is a widely used method for screening laptops at airport security. This process involves passing an X-ray beam through the laptop to create an image that can be analysed for security threats. X-ray scanning is generally considered safe for laptops, as X-rays do not affect electronic devices in any significant way. Laptops with hard drives are particularly unaffected, as hard drives store data magnetically and X-rays do not utilise magnets or magnetic forces. However, there are rare instances where travellers have reported issues with their laptops after X-ray scanning, such as distorted screens or WiFi connectivity problems. It is important to note that these issues may also be attributed to other factors, such as rough handling or unknown technical glitches.
When deciding between hand inspection and X-ray scanning for laptops at airport security, it is essential to weigh the pros and cons of each method. While hand inspection may provide peace of mind to those concerned about X-ray exposure, it can be a slower process and introduces the possibility of human error. On the other hand, X-ray scanning is generally recognised as safe for electronic devices, but there are rare reports of laptop issues post-scanning. Ultimately, travellers should make themselves aware of the procedures and take any necessary precautions, such as properly securing their devices and ensuring full battery charge before passing through security checks.
